I posted this before as I have an M wheel from my old 330. Never got a real response. I would think the wiring would still be present, but I am going to ask a tech at the dealership this weekend.

If you find out before hand please post back here. Thanks.

There is only one set of wires, BMW uses a bus system to tranmit button presses to the appropriate parts. But the other end has to read and act on the bus signals. Not sure what is different in the cars.

But salesmen will tell you ANYTHING to get you to buy the car. They figure that once it comes in, you won't be able to say no. Get it in writing, preferably from BMW NA.

Thanks for the reply. I know the head tech at the local dealer. Hopefully HE would not bs me since he is not a sales rep.
